<p>PURPOSE:To provide a deflection coil having a favorable coil curvilinear integral ratio in which deflection of wires or change of orders of the wires are prevented, and in which zig-zag winding of a multi-core parallel conductor is prevented by using the multi-core parallel conductor for a coil conductor for the deflection coil. CONSTITUTION:A saddle-shaped bobbin 2 for forming a deflection coil is provided with a coil winding groove 5 having flanges 3, and rounded surfaces 18 are provided on the forward end side of the flanges 3 of the coil winding groove 5. An inclination angle theta is formed to a groove side wall 13 of the coil winding groove 5 at a bobbom surface 10 of the coil winding groove 5. A multi-core parallel conductor 15 is inserted to the groove side wall 13 inside the coil winding groove 5 using a nozzle, and the multi-core parallel conductor 15 is wound in lamination to form a saddle-shaped deflection coil.</p> |
